AST files contain PCM16 sound data. They're used in Super Mario Galaxy for musics, and possibly in other games.
They contain an header followed by a BLCK chunk.
All the data in those files are big-endian, except where mentioned.
All the offsets are absolute (from begining of file), except where mentioned.
All the sizes are in bytes, except where mentioned.
=== AST header ===
The header is 64 bytes long.
